(01. 98-115) This invention relates to exhausting apparatus, angle members 6 and l are a plurality of upright and more particularly to an exhausting appaangle members ii, the pair at each end being ratus for removing obnoxious fumes from cleanconnected together at their upper and lower ends ing tanks or the like. by angle members l2 and the upper pair of mem- It is an object of the present invention to probers l2 are secured to longitudinally extending 5 vide a simple and efficient exhaust system for angle members 53 and I4 to form a substantially exhausting fumes from tanks without hindering rectangular framework to which an end plate l5 access to the tanks. and side plates i6 and I7 and the bottom plate 9 In accordance with one embodiment of the inmay be secured. The structure just described 10 vention, the cleaning tanks from which the fumes forms a substantially rectangular tank made up 10 are to be drawn and which may be tanks conof an angle iron framework and sheet metal sides taining hot solutions of chemical substances in and bottom. The left end of the tank 3 is left which parts are dipped to clean them before apopen as indicated at is. for communication with plying a plating to them, are positioned in a the exhaust p p large rectangular exhaust tank in which they The angle members l3 and '4 have a plurality 1e are laterally spaced one from another to provide 01" tapped holes formed therein to receive screws vertical passages therebetween, and bafiles are 2| a d 22 W c eXiend through Suitable p positioned at the tops of the vertical passages so res formed in baflle members 23.

A better understanding of the invention will be The Cleaning tanks 32 and 3 and other had by reference to the following detailed 13- cleaning tanks 3%, 35 and 36, are a conventional scription when taken in conjunction with the acyp f cl nin n h is p vi d at its 30 companying drawing, wherein ends with brackets 31 (Fig. 1) which rest upon 30 Fig. l is a vertical sectional view'taken longithe angle members It and i i to support the tanks tudinally of a tank of an exhaust system embody- 30 to 3b in the exhaust tank 3. Each of the end ing the features of the invention; angle members i2 is provided with a baifle 49 Fig. 2 is a sectional view taken on the line 2-2 which extends over the edge of the tanks 39 and 35 of Fig. l in the direction of the arrows, and 33 which are positioned at opposite ends of the 35 Fig. 3 is an enlarged fragmentary view of the exhaust tank 3. upper corner of the apparatus also taken along The tanks 3!) to 35 may be placed in any dethe line 2-2 of Fig. 1 in the direction of the arsired order in the exhaust tank 3, and when rows. placed in the order shown in Fig. l, the obnoxious 40 Referring now to the drawing wherein like reffumes generated by the chemical action of clean- 40 erence characters designate the same parts in ing parts, for example, in the tanks 3|, 32 and 33, the several views, a large tank designated by the will be drawn horizontally over the surface of numeral 3 is supported upon suitable standards the liquids in the tanks, and then drawn down- 4-4 and has connected to the left hand end wardly through the passages formed by the thereof (Fig. 1) an exhaust pipe 5 which may sides of the cleaning tanks directly beneath the 45 be connected to a suitable exhaust fan (not bafiles 23, through the bottom portion of the exshown). The tank 3 is made up of a plurality haust tank and thence out through the exhaust of metallic sheets and an angle iron framework. pipe 5. It will be noted that the edges of the The framework comprises a pair of base angle tanks 34, 35 and 36 extend somewhat higher than members 6 and "I which are bent at 8 so that the do the edges of the tanks 38 to 33, inclusive. In 50 bottom plate 9 of the tank 3 will be inclined the embodiment of the invention disclosed, the downwardly towards the center for drainage purtanks 34, 35 and 36 contain fluids which do not poses, a suitable aperture l0 being formed in the give off obnoxious fumes and, therefore, it is plate which may or may not be fitted with a not necessary to exhaust them. Therefore, closure member (not shown). Secured to the baffles 23 which engage the left and right edges 55 of the tanks 35 and 35, respectively, do not have an opening between the bafile and the tank to permit the air from the tanks to be drawn out through the exhaust system. It will also be noted that a pair of U-shaped caps 4i have been placed over the adjoining edges of the cleaning tanks 3 and 3'5, and 35 and 36, so that the efficiency of the exhausting of the tanks which give off obnoxious fumes will not be interfered vfith. With the arrangement shown, the cleaning tanks 39 to 36 may be placed in the exhaust tanks in any desired order and any selected ones of the cleaning tanks may have the obnoxious fumes generated therein drawn off through the exhaust system by simply changing the position of the baffles 23 and placing the U-shaped caps d! in the desired positions.

Although a particular embodiment of the invention has been described hereinbefore, it will be understood that the invention is subject to many modifications without departing from the scope of the appended claim.

What is claimed is:

In an apparatus for removing fumes from a plurality of adjacent cleaning tanks, a relatively large exhaust tank having an open top, and means for supporting a plurality of relatively small cleaning tanks therein in spaced relation toprovide vertical passages between the cleaning tanks and the walls of the exhaust tank and between adjacent cleaning tanks, a plurality of bafiles supported by said exhaust tank and positioned adjacent edges of the cleaning tanks, means for creating a suction in the exhaust tank thereby to withdraw fumes from the surfaces of the cleaning tanks and into position to be deflected by the bafiies downwardly through the passages formed between the cleaning tanks and then horizontally beneath the cleaning tanks.
